Ideal solution for boiler replacement
The YUTAKI S80 heat pump is able to produce hot water at 80°C
with -20°C outdoor temperature (without supplementary power
supply), it is thus ideal for the refurbishment market and adapts to
all types of existing installation.
One of the best COP on the Market
YUTAKI S80 has one of the best COP on the Market: 4.36
(RWH 4.0FSVNFE - conditions 7°C/35°C). Its unique design
allows it to maintain high performance year-round with
extremely high SCOP (seasonal COP)
Wide Power
The wide range of Yutaki
S80 can address all heating
and domestic hot water
production needs in
the residential market
(refurbishment + new build).
Easy maintenance
Yutaki S80 has been designed
to make the professional's work
easier (installation + maintenance).
All main components are
accessible from the front.
For instance, the electrical panel
may be easily removed.

Operation with verylowoutside temperature!
Operation with mild outside temperature!
Exclusive adjustment system
YUTAKI S80 has an “intelligent” control able to adapt its
operation (with R410A refrigerant cycle or using the second
R134A refrigerant stage) by using an algorithm that takes
into account: the outdoor temperature condition (heating
and/or domestic hot water), performance optimisation and
defrosting cycles.
High yearly performance
During less cold periods (e.g. mid-season) or when heating
requirements are lower, Yutaki-S 80 adapts its operation to
optimise its performance.
The second refrigerant stage is thus by-passed, and hot water
production is thus assured through the first refrigerant stage,
avoiding useless simultaneous operation of two compressors
to the advantage of better seasonal energy efficiency.
During very cold periods (e.g. in the middle of winter) or
when heating requirements are high, Yutaki-S 80 adapts its
operation to optimise its performance.
The By-pass of the first stage is then closed and the second
refrigerant stage is activated, thus satisfying the requirement
for high temperature hot water production.
« SMART CASCADE » Hitachi is a unique
and intelligent concept which optimises
heat pump efficiency. Depending on a
number of parameters, the controller decides whether
one or both compressors should operate. This translates
into considerable energy savings.
YUTAKI S80 has standard dimensions (l x D: 595 x 695 mm) to easily integrate
in all types of homes. When it is installed underneath the DHW module, YUTAKI
S80 is in any case shorter than 2 m (mod. 195L). Plumbing connections with
standard supplied flexible hoses, designed to reduce and aid the installer's
workload.
